OK. I hope you canl pass this on to Adam then (but in PM this time

)
Only small files (up to 100kB) ie. JPG previews can be attached, simply by choosing the file in the attachment box (not visible in quick reply - you have to click on "post reply"). It would be really good if he posted previews of leaderheads before animating.
In order to upload large files, you do not attach the files to post, but use the easy upload feature. Here is an official tutorial on how to do this:

How to add new graphics to the mod - it's a long story - you have to read articles in tutorials section. But again, he doesn't have to ie. add lizardmen to the mod, since they are already there as many other things that come with WH-Mod 2.0 (I mean it's generally better to wait for it, rather than to edit 1.1). I am eagerly awaiting to see the leaderheads, though I can't promise that they'll be included immediately, since one slann is in the works already and I don't have any units for Chaos Dwarfs yet (but I would really like to include this faction at some point).
p.s. Oh yes, last time when playing MEM, I had to capture Prague I'm afraid

If it's disconnecting you, then it's definetely the matter of your connection. You need WinACE or WinRAR anyway, but this doesn't affect your download, since you need them only after you got the files. Try again few times, if not, try from friend's place etc.
